Take your flash off your camera & expand your creative capabilities with this 2.4 G Hz wireless triggering system. This trigger set will allow you to trigger your flash over 100 meters away. The 4-channel, radio-enabled circuitry prevents your flash from being triggered by other flash units around you, making it perfect for photographing at events or on location. Additionaly the system can be used as either a wired or wireless remote shutter release for your camera. The transmitter is equipped with a hot shoe for camera mounting & the receiver may be mounted to a cold shoe or a 1/4"-20 tripod or stand mount. Other features include a test/shutter button & a status LED to verify operations. This kit can also be used with Olympus & Sony cameras if purchased with the 06 or S6 Shutter Release Cable (sold separately). Please note that these triggers do not transmit TTL information.
